Abstract
Description
Technical Field
[0001] This utility model relates to the field of elastic band technology, and more specifically, to a wear-resistant elastic band. Background Technology
[0002] Elastic bands, usually made of woven rubber filaments or strips, are commonly used in clothing accessories. They help garments stay in place better on the wearer's body, and the elasticity of the bands can also help to shape the wearer's figure.
[0003] When using existing elastic bands, the elastic band is placed at the point where the wearer needs to be secured. At this time, the elastic band will deform under the influence of the wearer's body and release elastic potential energy. Through the elastic potential energy released by the elastic band, the elastic band and the wearer's body can be fixed together, thereby achieving the effect of fixing the elastic band and the wearer's body together.
[0004] However, after repeated use, washing, and drying, the elastic fibers inside the elastic band become fatigued, resulting in reduced elasticity and affecting the band's ability to secure the wearer.
[0005] Therefore, a new solution is needed to address this problem. Utility Model Content
[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a wear-resistant elastic band, which solves the problem that after repeated use, the elastic fibers in the elastic band will become fatigued, resulting in a decrease in the elasticity of the elastic band and affecting the fixation effect of the elastic band on the wearer.
[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a wear-resistant elastic band, including an elastic band body and two rotating blocks rotatably connected to each other. The two rotating blocks are provided with sliding grooves for the elastic band body to slide on. The side walls of the two rotating blocks are provided with through grooves that communicate with the sliding grooves. A limiting block is slidably connected in the through groove. The elastic band body is provided with several through holes for the limiting block to be inserted. The two rotating blocks are interlocked by a snap-fit assembly. When the two rotating blocks are interlocked, the limiting block is inserted into the through hole. When the two rotating blocks are uninterlocked, the limiting block is in contact with the outside.
[0008] By adopting the above technical solution, after the elastic band has been used, washed, and dried multiple times, the two rotating blocks are disengaged by the snap-fit assembly. The two rotating blocks are then moved to rotate, simultaneously releasing the two limiting blocks, which move outward along the through groove and separate from the through hole on the elastic band body. Then, the elastic band body is pulled, causing it to move along the sliding groove. At this point, the elastic band body located on the two rotating blocks is affected. The elastic band body is shortened. When the elastic band body is shortened to a suitable length, it drives the two rotating blocks to rotate and engage with each other. At the same time, the limiting block is affected by the rotating blocks, causing the limiting block to move towards the slide groove and insert into the through hole of the elastic band body. At this time, the elastic band body is affected by the limiting block, making it unable to move. This achieves the effect of adjusting the length of the elastic band body. When the elastic fibers in the elastic band body experience fatigue, adjusting the length of the elastic band body can increase the deformation range of the elastic band body, increase the release of elastic potential energy, and improve the fixation effect of the elastic band on the wearer.
[0009] The present invention is further configured such that: the snap-fit assembly includes a rotating rod rotatably connected to one of the rotating blocks, a snap-fit block is fixedly connected to the rotating rod, the rotating block has a groove for the rotating rod to slide, and the other rotating block has a slot for the snap-fit block to engage.
[0010] By adopting the above technical solution, when it is necessary to drive the two rotating blocks to rotate, a pulling force is applied to the locking block to disengage the locking block and the locking groove. At the same time, the rotating rod is driven to move upward along the groove. Then, the locking block is moved to drive the locking block to rotate around the rotating rod, so that the locking block and the rotating block with the locking groove are separated from each other. At this time, the two rotating blocks are no longer restricted and can be driven to rotate. When it is necessary to restrict the rotation of the two rotating blocks, the side walls of the two rotating blocks are pressed together. Then, the locking block is rotated to the locking groove and pressure is applied to the locking block to make the locking block enter the locking groove and engage with the locking groove. At this time, the two rotating blocks are restricted and cannot rotate.
[0011] The present invention is further configured such that: a limiting piece is fixedly connected to the side wall of the limiting block, and a placement groove for placing the limiting piece is provided on the side wall of the sliding groove.
[0012] By adopting the above technical solution, it is possible to prevent the limiting block from falling out of the through slot and into the outside, thus avoiding affecting normal use.
[0013] The present invention is further configured such that: an observation port communicating with the slide groove is opened on the side of the two rotating blocks away from the limiting block, and the observation port and the limiting block are concentrically arranged.
[0014] By adopting the above technical solution, when the limiting block enters the through hole on the elastic band body, it is easy for the wearer to observe whether the limiting block has entered the through hole, which facilitates the fixation of the elastic band body.
[0015] The present invention is further configured such that: a plurality of the through holes are provided with a rim.
[0016] By adopting the above technical solution, the wear resistance of the through hole of the elastic band body can be improved, preventing the through hole from being damaged after repeated friction between the limiting block and the through hole, and improving the service life of the through hole.
[0017] The present invention is further configured such that: the elastic band body includes elastic yarn and abrasion-resistant yarn, and the elastic yarn and abrasion-resistant yarn are woven together in a twill weave.
[0018] By adopting the above technical solution, elastic yarn and abrasion-resistant yarn are woven into the elastic band body by twill weaving. This method can make the elastic yarn and abrasion-resistant yarn woven more tightly, thereby improving the abrasion resistance of the elastic band body.
[0019] In summary, this utility model has the following beneficial effects: after the elastic band has been used, washed, and dried multiple times, the length of the elastic band body can be adjusted by setting two rotating blocks and a limiting block. When the elastic fibers in the elastic band body experience fatigue, adjusting the length of the elastic band body can increase the deformation range of the elastic band body, increase the release of elastic potential energy, and improve the fixation effect of the elastic band on the wearer.

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0027] A type of abrasion-resistant elastic band, such as Figures 1-3 As shown, the device includes an elastic band body 1 and two rotating blocks 2 rotatably connected to each other. The two rotating blocks 2 have grooves 3 for sliding the elastic band body 1. The side walls of the two rotating blocks 2 have through grooves 4 that communicate with the grooves 3. A limiting block 5 is slidably connected within the through groove 4. The elastic band body 1 has several through holes 6 for inserting the limiting block 5. The two rotating blocks 2 are interlocked by a snap-fit assembly. When the two rotating blocks 2 are interlocked, the limiting block 5 is inserted into the through hole 6. When the two rotating blocks 2 are uninterlocked, the limiting block 5 is inserted into the through hole 6. Block 5 is in contact with the outside world. After the elastic band is used, washed and dried multiple times, the two rotating blocks 2 are unhooked by the snap-fit component and the two rotating blocks 2 are moved to make them rotate. At the same time, the two limiting blocks 5 are unrestrained and move outward along the through groove 4 and separate from the through hole 6 on the elastic band body 1. Then the elastic band body 1 is pulled to move along the slide groove 3. At this time, the elastic band body 1 located on the two rotating blocks 2 is affected, and the length of the elastic band body 1 is shortened.
[0028] When the elastic band body 1 is shortened to a suitable length, it drives the two rotating blocks 2 to rotate and engage with each other. At the same time, the limiting block 5 is affected by the rotating blocks 2, causing the limiting block 5 to move towards the slide groove 3 and insert into the through hole 6 of the elastic band body 1. At this time, the elastic band body 1 is affected by the limiting block 5, making it impossible for the elastic band body 1 to move. This achieves the effect of adjusting the length of the elastic band body 1. When the elastic fibers in the elastic band body 1 experience fatigue, adjusting the length of the elastic band body 1 can increase the deformation range of the elastic band body 1, increase the release of elastic potential energy, and improve the fixation effect of the elastic band on the wearer.
[0029] like Figures 1-3 As shown, the snap-fit assembly includes a rotating rod 7 rotatably connected to one of the rotating blocks 2, a snap-fit block 8 fixedly connected to the rotating rod 7, a groove 9 for the rotating rod 7 to slide on the rotating block 2, and a snap-fit groove 10 for the snap-fit block 8 to engage on the other rotating block 2. When it is necessary to drive the two rotating blocks 2 to rotate, a pulling force is applied to the snap-fit block 8 to disengage the snap-fit block 8 from the snap-fit groove 10, and at the same time, the rotating rod 7 is driven to move upward along the groove 9. Then, the snap-fit block 8 is moved to rotate around the rotating rod 7, so that the snap-fit block 8 separates from the rotating block 2 with the snap-fit groove 10. At this time, the two rotating blocks 2 are no longer restricted and can be driven to rotate. When it is necessary to restrict the rotation of the two rotating blocks 2, the side walls of the two rotating blocks 2 are pressed together, and then the snap-fit block 8 is rotated to the snap-fit groove 10 and pressure is applied to the snap-fit block 8 to enter the snap-fit groove 10 and engage with the snap-fit groove 10. At this time, the two rotating blocks 2 are restricted and cannot rotate.
[0030] like Figures 1-3 As shown, the limiting block 5 is fixedly connected to the side wall of the limiting piece 11, and the side wall of the slide groove 3 is provided with a placement groove 12 for placing the limiting piece 11, which can prevent the limiting block 5 from falling into the outside from the through groove 4 and avoid affecting normal use. The two rotating blocks 2 have observation ports 13 on the side away from the limiting block 5 that are connected to the slide groove 3. The observation ports 13 and the limiting block 5 are concentrically set, so that when the limiting block 5 enters the through hole 6 on the elastic band body 1, it is convenient for the wearer to observe whether the limiting block 5 has entered the through hole 6, which is convenient for fixing the elastic band body 1.
[0031] like Figures 1-3 As shown, several through holes 6 are provided with a binding edge 14, which can improve the wear resistance of the through holes 6 of the elastic band body 1, prevent the through holes 6 from being damaged after repeated friction between the limiting block 5 and the through holes 6, and improve the service life of the through holes 6.
[0032] like Figures 1-3As shown, the elastic band body 1 includes elastic yarn 15 and abrasion-resistant yarn 16. The elastic yarn 15 and abrasion-resistant yarn 16 are woven together in a twill weave. The elastic band body 1 is formed by weaving the elastic yarn 15 and abrasion-resistant yarn 16 in a twill weave. This method can make the elastic yarn 15 and abrasion-resistant yarn 16 weave more tightly, thereby improving the abrasion resistance of the elastic band body 1.
[0033] The usage process of this utility model is as follows: After the elastic band has been used, washed and dried multiple times, a pulling force is applied to the locking block 8 to cause the locking block 8 and the locking groove 10 to disengage. At the same time, the rotating rod 7 is driven to move upward along the groove 9. Then, the locking block 8 is moved to rotate around the rotating rod 7, causing the locking block 8 to separate from the rotating block 2 with the locking groove 10. At this time, the two rotating blocks 2 are no longer restricted and can be driven to rotate. At the same time, the two restricting blocks 5 are no longer restricted and move outward along the through groove 4 and separate from the through hole 6 on the elastic band body 1. Then, the elastic band body 1 is pulled to move along the sliding groove 3. At this time, the elastic band body 1 located on the two rotating blocks 2 is affected, causing the length of the elastic band body 1 to shorten.
[0034] When the elastic band body 1 is shortened to a suitable length, it drives the two rotating blocks 2 to rotate and engage with each other. At the same time, the limiting block 5 is affected by the rotating blocks 2, causing the limiting block 5 to move towards the slide groove 3 and insert into the through hole 6 of the elastic band body 1. At this time, the elastic band body 1 is affected by the limiting block 5, making it impossible for the elastic band body 1 to move. This achieves the effect of adjusting the length of the elastic band body 1. When the elastic fibers in the elastic band body 1 experience fatigue, adjusting the length of the elastic band body 1 can increase the deformation range of the elastic band body 1, increase the release of elastic potential energy, and improve the fixation effect of the elastic band on the wearer.
[0035] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
